Improved Tent Map and Its Applications in Image Encryption
Xuefeng Liao · International Journal of Security and Its Applications · 2015
In this paper, an improved tent map chaotic system with better chaotic performance is introduced.The improved tent map has stronger randomness, larger Lyapunov exponents and C 0 complexity values compare with the tent map.Then by using the improved tent map, a new image encryption scheme is proposed.Based on all analysis and experimental results, it can be concluded that, this scheme is efficient, practicable and reliable, with high potential to be adopted for network security and secure communications.Although the improved tent chaotic maps presented in this paper aims at image encryption, it is not just limited to this area and can be widely applied in other information security fields.
